/6 198 rods needed badly

I am not so sure that you NEED these 198 rods.... If I were you, and on a limited budget, I'd rebuild the stock setup, paying a lot of attention to ring end-gap specs, and assemble that motor with about .006" piston to cylinder wall clearance, and run 20 pounds of boost with 18 degrees of spark-timing and my guess is that it will really scoot!!!

Boost can make up for ALL KINDS of design errors...

I'd forget those long rods... David Reher said in an article in NHRA's "National DRAGSTER", "a connecting rod's only function is to connect the crankshaft to the piston." He doesn't buy the rod-length advantage, after a gazillion dyno tests...

That's good enough for me...

does it make hp? no but it sure does add longevity and other measurable variables if the change is big enough!
